Supported Commands

In a Telegram chat, type @CryptoraBot and then any of these commands to use Cryptora:

[cryptocurrency] – Type the name of any cryptocurrency, and Cryptora will retrieve essential information (price, market cap, circulating supply, and 24 hour percent change) and display it in a list. You can also type the cryptocurrency's symbol. For example, you can type bitcoin or BTC to get essential information about Bitcoin. The bot is not case sensitive, so you can type in any valid cryptocurrency name or its symbol in lower case or upper case. You can also type multiple cryptocurrencies, separated by commas, and send a list of cryptocurrency prices, percent changes, or market capitalizations in a single message. Cryptora automatically filters out duplicate and invalid entries. So, typing xrp, iota, xmr, nano, bitcoin will get you a list of their prices, market capitalizations, and percent changes that you can share with a chat.
news - Retrieve the latest headlines from a variety of cryptocurrency news sites - aggregated by CryptoCompare – and display them in a list. You can choose to share the article with your chat, or you can browse the latest cryptocurrency headlines.
global - Retrieve global statistics from CoinMarketCap, including the total market capitalization, the total 24 hour volume, bitcoin's dominance, and the number of active cryptocurrencies and markets.
coinbase pro - Retrieve the trading price of Bitcoin, Bitcoin Cash, Litecoin, Ethereum, and Ethereum Classic from the Coinbase Pro trading exchange.
[cryptocurrency] [date] - Type this command, replacing [cryptocurrency] with your desired cryptocurrency, and [date] with a date formatted in MM/DD/YYYY format (or Month Day, Year format), and Cryptora will retrieve the high, low, opening, and closing price - as well as the market capitalization - of the cryptocurrency on that date, if data is available. Relative dates work as well, so typing ethereum 2 weeks ago or ethereum yesterday will get you information about ethereum two weeks ago and yesterday, respectively. Note that for relative dates, your numerical value must be a numeral and not a word - for example, ethereum two weeks ago will not work, while ethereum 2 weeks ago will.
top [x] - Type this command (replace [x] with any number less than or equal to 50) to see the top x cryptocurrencies, ranked by their market capitalization.
[x] [cryptocurrency] - Type this command (replace [x] with any number, and [cryptocurrency] with your desired cryptocurrency) to instantly convert an amount of cryptocurrency to U.S. dollars.
$[x] [cryptocurrency] - Type this command (replace [x] with any number, and [cryptocurrency] with your desired cryptocurrency) to instantly convert an amount of U.S. dollars to the desired cryptocurrency.

How it was built

Cryptora is a Python 2.7 program. It was built using the python-telegram-bot framework. Data is retrieved from CoinMarketCap, using a combination of API access and webscraping. News articles are retrieved from CryptoCompare. The bot is hosted on an Amazon AWS EC2 server, using a Ubuntu-based Docker container.
